Summary:
Currently when --passes is used, any passes specified via -foo are
ignored. Explicitly bail out when that happens.
This requires changing some tests. Most were straightforward, but
codegenprepare-produced-address-math.ll is tricky. One of its RUNs runs
CodeGenPrepare. I tried porting CodeGenPrepare to the NPM, but ended up
getting stuck when I needed a TargetMachine. NPM doesn't have support
for MachineFunctions yet. So I just deleted that RUN line, since it was
mass-added in https://reviews.llvm.org/D54848 and is likely not that
useful.

As it's causing some bot failures (and per request from kbarton).
This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

There are two nontrivial details here:
* Loop structure update interface is quite different with new pass manager,
so the code to add new loops was factored out
* BranchProbabilityInfo is not a loop analysis, so it can not be just getResult'ed from
within the loop pass. It cant even be queried through getCachedResult as LoopCanonicalization
sequence (e.g. LoopSimplify) might invalidate BPI results.
Complete solution for BPI will likely take some time to discuss and figure out,
so for now this was partially solved by making BPI optional in IRCE
(skipping a couple of profitability checks if it is absent).
Most of the IRCE tests got their corresponding new-pass-manager variant enabled.
Only two of them depend on BPI, both marked with TODO, to be turned on when BPI
starts being available for loop passes.
